" sMonn-wArue ArrAaATUs Application filed August 9, 1929.. Serial No. 384,730.

'I he invention relates to improvements in smoke washing apparatus applicable to any of the known types of chimney structure and particularly serviceable as a means of s entirelyeliminating soot, ashes, dbris, and other objectional particles from the smoke emanating from chimney stacks and other exhaust ducts of a like nature.

The invention comprises supporting means at and upon the exhaust end of the chimney or other like structure and of the attachment thereto of a trough or water reservoir having mounted thereon means supporting an accumulator hood or dome carrying a'suitable baille means arranged to pocket an amount of the gases emanating from the chimney to form a cushion or buffet body for the smoke, gases, etc., passing therefrom, and upon which cushion said smoke, gases, etc. impinge and aredeflected through a water curtain or screen formed by a water supply disposed in said dome, thus washing and clarifying said smoke and gases and precipitatin all deleterious substances therefrom, to t e trough or reclamation means whence it is returned through suitable drainage means to anyl point of deposit, permitting only the substantially clarified and purified vapors to emit'from the stack.

The essential4 object of the invention re,n sides in the super-imposing upon the emitting end of a chimney or stack of a specially formed deflector hood provided with a bailie wall arranged to accumulate an amount of gas to act as a builer cushion against which the smoke contacts to 'form a vacuum head and deect the smoke and gases therefrom through the water curtain, thoroughly washing said smoke and precipitating all solids 1U to the reclamation trough whence same may be carried off through suitable gravity eX- haust means, the action of the smoke and gasses passing from such chimney or stack functioning as a draft or vacuum head for the generator unit.

In the following there is described one em bodiment of the invention, the features there.- ofvbeing more clearly defined hereinafter in the claims. w

5U In the. drawings, Fig. 1 is a vertical sectional view of the smoke washin apparatus as applied to the emitting end o any of the known types of chimney or stack ends; Fig. 2 is a plan cross section on the line 2 2 of Fig. 1 of the accumulator trough showing in cross section the deflector head and the water ejector means for forming the clarifying water curtain; Fig. 3 is a cross sectional view of the water head showing the position thereon of a water ejector nozzle or nipple; and Fig. 4 is an under elevation of the water head showing the position therein of the ejector nozzles and of the specific formation of thewater ducts or apertures forncasting a fan like stream to form the water curtain or washing means. A v

In the following similar numerals of references indicate similar parts throughout the drawings, forming part hereof.

ln the drawings 1 designates a chimney or stack structure havin disposed upon its exhaust or emitting end a secondary chimney structure comprising'a supporting collar or sleeve 2, carrying an annular rib 3 to which an accumulator or reception trough 4 is attached, said trough 4C receiving part of its support upon the rim or top of said exhaust structure 1. v

Trough 4 is of partly frustra-conical form inverted and provided at its lower portions with a horizontal section 5 to form between the conical wall 6 and the outer surface 7 of supporting sleeve 2, a water or reclamation chamber 8, and at the top of said conical wall 6 a circular sleeve 9 forming the'exhaust or emitting end of the stack 1. Wall 6 of trough 4 has mounted thereon a series of supporting brackets 1() having disposed therein bolts 11 which have mounted thereon and adjustable vertically with relation thereto a cone-like accumulator hood or dome 12. The peripheral edge of dome 12 has mounted thereon clips justably secured thereon by means of nuts 14.-. Said dome or hood 12 has mounted on its under side and within the conical confines thereof a baille sleeve or annular plate 15 arranged to form the means of accumulating of gas from the stack to form the smoke cushion or buffer deflector means. A water head, 16,

\ 13 engaging said bolts 11 the same being adp from stack 1 -must pass formation 21 atmosphere, providing therefor a washingl means through which every particular of smoke, gas, heavier than air particles ctc. to be completely clarified. l

Within dome 12 and above baffle sleeve 15, a lgas chamber 23 is formed to receive the gases, etcz, from stack 1 to .act as the draft or semi-vacuuous "means for assisting the draft' of said stack 1.

Water head 16 is connected with a fresh water supply pipe 24 connected with any source of Water supply, and section 5 of accumulator 4 has mounted therein an exhaust or waste lpipe 25 arranged to carry olf by gravity the sludge and other substances washed from the smoke, gases, etc., emitted by the chimney or stack.

The invention may be varied in structural form in many ways without departing from the spirit of the same as is shown, described and claimed herein.

What is claimed and desired to secure by Letters Patent of the United Statses is:

1. A. device of the character described comv prising an auxiliary supporting means disposedupon a chimney outlet, a reservoir mounted thereon, a receiving chamber formed in said reservoir between the outer Wall of said auxiliary supporting means and the inner wall of said reservoir, supporting means carried by said reservoir, anaccumu'lator hood adjustably disposed upon the supporting means in said reservoir, an annular vertically disposed baille means mounted in said hood arranged to form within the conical dome thereof a gas cushioning chamber, awater head mounted in said hood on the outer wall of said balile means provided with a plurality of nip les having apertures adapted to project a an like spray across the vent between said reservoir and hood to 'form the water curtain for clarifying the smoke and .gases emitted by said chimney.

l2. A device of the character described comprising a secondary chimney structure mount'- ed on the exhaustend of a smoke stack; a

partly -conically shaped reservoir mounted thereon, a water and sludge receiving chamber formed in said reservoir, supporting `brackets carried by said reservoir and disposed on the conical walls of said reservoir,

supporting bolts mounted `in said. brackets,A

an accumulator hood mounted on said bolts and adjustable vertically with relation thereto, and annular baffle means mounted in said hood and dependingtherein toform within said hood a gas cushioning chamber, a Water head mounted 1n said hood and disposed yaround the outside of said baiile means provided with a plurality of spray nipples arranged to pro]ect an uninterrupted water l emitting end of a chimney, an inverted conically shaped reservoir mounted on said collar, a sludge receiving chamber in said reservoir, supporting brackets mounted on the inside conically shaped walls of said reservoir, a series of'supporting bolts mounted in said brackets, an accumulator hood mounted on said bolts and adjustable vertically to and away from the exhaust end of said collar to vary the vent between said reservoir and hood, an annular baile sleeve mounted in the dome of said hood, a water head mounted in said hood and disposed around the outer wall of said baffle sleeve adapted to project a Water-,curtain across the vent between said reservoir and hood to the chamber in said reservoir, a plurality of'nipple's mounted in said water head provided with emitting apertures arranged to project said water curtain in an annular uninterrupted column circumferentially around the exhaust end of said chimney to clarify the smoke passing through said vent, a pipe connection forming means for supplying water tovsaid water head, and an exhaust pipe connection mounted in said reservoir in the receiving chamber thereof arranged to carry od the sludge precipitated therein.

In testimony whereof I affix my signature. CHARLES M. GERHOLD.
